DESCRIPTION

 The TPS51518 is a single phase, D-CAP™/

 D-CAP2™ synchronous buck controller with 2-bit VID

inputs which can select up to four independent

 externally programmable output voltage levels where

 full external programmability in the voltage level, step

setting and voltage transition slew rate is desired. It is

 used for GFX applications where multiple voltage

The TPS51518 supports all POS/SPCAP and/or all

 ceramic MLCC output capacitor options in

applications where remote sense is a requirement.

 Tight DC load regulation is achieved through external

 programmable integrator capacitor.

 The TPS51518 provides full protection suite,

 including OVP, OCL, 5-V UVLO and thermal

 shutdown. It supports the conversion voltage up to

28 V, and output voltages adjustable from 0.5 V to2 V.

The TPS51518 is available in the 3 mm × 3 mm,

QFN, 0.4-mm pitch package and is specified

from –10°C to 105°C.
